Pylint不能在OS X上使用Emacs GUI;从命令行工作 [英] Pylint not working with Emacs GUI on OS X; works from command-line
问题描述
当从命令行（ emacs filename.py ）运行时，flymake和pylint可以一起工作。错误突出显示正确。 （虽然我无法使用鼠标悬停来获取错误详细信息，因为它是文本模式。）
当从GUI（Carbon Emacs）运行时，Flymake会立即返回，第一个在< module> 中突出显示错误。第一行即使在Hello World脚本中也显示错误。）我希望在GUI模式下正常工作，以便我可以使用鼠标导航（我知道，我知道）并使用工具提示来获取详细信息在pylint报告错误。
我安装pylint easy_install pylint ，pylint和epylint脚本是在〜/ py / scripts 中。我将该目录添加到我的PATH中.bashrc：
export PATH = $ PATH：〜/ py / scripts
（我的.profile是我的.bashrc的符号链接）
$ b $我意识到Emacs-GUI没有加载我的.bashrc的路径，所以我创建了一个〜/ .MacOSX / environment.plist文件，设置PATH变量与终端中看到的完整路径。 p>
现在在Emacs-GUI（getenvPATH）输出显示正确：
/ usr / bin：/ bin：/ usr / sbin：/ sbin：/ usr / local / bin：/ usr / local / git / bin ：/ usr / X11 / bin：/ Users / schof / py / scripts：/ usr / X11R6 / bin
类似地， Ch v exec-path 的输出正确显示：
$ / $ / $/ usr / bin/ bin/ usr / sbin/ sbin/ usr / local / bin/ usr / bin/ Users / schof / py / scripts/Applications/Emacs.app/Contents/MacOS/libexec/Applications/Emacs.app/Contents/MacOS/bin/ usr / X11R6 / bin）
我没有进一步的想法来解决这个问题。我绝对不是一个emacs大师，所以有可能我在这里缺少一些明显的东西;随时要求更多的细节。
OS X 10.6.7;碳Emacs 22.3.1; pylint 0.23.0。

没有这个信息，我不会推测可能的问题。 / p>
有一个窍门来避免 environment.plist 方法，BTW;您可以让Emacs询问您的常规shell是否适用您的首选路径：
（defun set-exec-path-from-shell- PATH（）
（let（（path-from-shell（replace-regexp-in-string
[\t\\\
] * $
（shell-command-to-string$ SHELL --login -i -c'echo $ PATH'））））
（setenvPATHfrom-shell）
（setq exec -path（split-string path-from-shell path-separator））））
（当（和window-system（eq system-type'darwin））
;;启动时从Emacs.app或类似的，确保$ PATH
;;是相同的用户将看到在Terminal.app
（set-exec-path-from-shell-PATH））
（从我的Emacs config ，其中包含一堆flymake代码，其中包括使用 pyflakes 的python配置，因此您可能需要查看。）
更新：现在你已经添加了详细的输出，我看到你的〜/ py / epylint程序找不到 pkg_resources ，它指向 PYTHONPATH 错误。所以，使用上述技术的变体，尝试这样：
（defun setenv-from-shell（varname）
（setenv varname（replace-regexp-in-string
[\t\\\
] * $
（shell-command-to-string（concat$ SHELL --login -i -c'echo $varname'）））））
（setenv-from-shellPYTHONPATH）
When run from the command-line (emacs filename.py) flymake and pylint work perfectly together. Errors are highlighted properly. (Although I can't tooltip hover to get error details because it's text-mode.)
When run from the GUI (Carbon Emacs) Flymake returns immediately, and the first line in the file is highlighted with the error "in <module>". The first line is shows the error even on a "Hello World" script.) I'd like to get it working properly in GUI mode so that I can navigate with the mouse (I know, I know) and use tooltips to get details on the pylint reported errors.
I installed pylint with "easy_install pylint", and the pylint and epylint scripts are in "~/py/scripts". I added that directory to my PATH in my .bashrc:
export PATH=$PATH:~/py/scripts
(My .profile is a symlink to my .bashrc.)
I realized that Emacs-GUI was not loading the path from my .bashrc, so I created a ~/.MacOSX/environment.plist file, setting the PATH variable with the full PATH I see in the terminal.
Now in Emacs-GUI "(getenv "PATH")" the output appears correct:
"/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/X11/bin:/Users/schof/py/scripts:/usr/X11R6/bin"
Similarly, the output of "C-h v exec-path" appears correct:
("/usr/bin" "/bin" "/usr/sbin" "/sbin" "/usr/local/bin" "/usr/local/git/bin" "/usr/X11/bin" "/Users/schof/py/scripts" "/Applications/Emacs.app/Contents/MacOS/libexec" "/Applications/Emacs.app/Contents/MacOS/bin" "/usr/X11R6/bin")
That leaves me with no further ideas for how I should resolve this. I'm by no means an emacs guru, so it's possible I'm missing something obvious here; feel free to ask for more details.

To more clearly see what's going wrong, increase flymake's log level, then look in *messages*:
(setq flymake-log-level 3)
Without that info, I wouldn't speculate on the likely problem.
There's a trick for avoiding the environment.plist approach, BTW; you can get Emacs to ask your regular shell for your preferred PATH:
(defun set-exec-path-from-shell-PATH ()
(let ((path-from-shell (replace-regexp-in-string
"[ \t\n]*$"
""
(shell-command-to-string "$SHELL --login -i -c 'echo $PATH'"))))
(setenv "PATH" path-from-shell)
(setq exec-path (split-string path-from-shell path-separator))))
(when (and window-system (eq system-type 'darwin))
;; When started from Emacs.app or similar, ensure $PATH
;; is the same the user would see in Terminal.app
(set-exec-path-from-shell-PATH))
(That's lifted from my Emacs config, which has a bunch of flymake code in it, including a config for python using pyflakes, so you might want to take a look.)
Update: Now that you've added the verbose output, I see that your ~/py/epylint program can't find pkg_resources, which points to PYTHONPATH being wrong. So, using a variation on the above technique, try this:
(defun setenv-from-shell (varname)
(setenv varname (replace-regexp-in-string
"[ \t\n]*$"
""
(shell-command-to-string (concat "$SHELL --login -i -c 'echo $" varname "'")))))
(setenv-from-shell "PYTHONPATH")
